Question about the latest chapter

How long ago did you think Oda came up with Imu and do you think he’s had their design like this for awhile? Or is it something you think he came up with quickly. Imu looks insanely sick, I’m curious about how long Oda has this whole Imu plot planned out for.

Another random question, do you like this whole five elders/WG/Imu story or do you guys think it’s too over the top. Thinking back to where one piece started and came from it’s crazy to think of how far the story has came and how much has been introduced. Feels more than just luffy assembling a crew to find the one piece like it started out to be. Not that it’s bad i love the whole show and manga, feels like we’ve been through so many turns and hoops haha
